The young fellow is about to marry and asks his grandfather how often a married couple should have sex. His grandfather tells him, "When you first get married, you want it all the time, maybe several times a day; later on, maybe once a week. As you get older, you have sex maybe once a month. When you get really old, you are lucky to have it once a year, maybe on your anniversary." The young fellow asks, "How about you and Grandma?" His grandfather replies, "Oh, we just have oral sex now. She goes into her bedroom and I go into my bedroom. She yells, 'F**k you,' and I holler back, 'F**k you, too!'"
